本章规定了安装在固定位置的标称水平圆柱形储罐的手动校准方法。适用于直径不超过4米、长度不超过30米的卧式储罐。 这些方法适用于地面或地下的绝缘和非绝缘储罐。该方法适用于带压储罐，也适用于转向节碟形端和平端圆柱形储罐，以及椭圆形和球形封头储罐。本章适用于从水平面倾斜10%的储罐，前提是对测量的倾斜进行校正。 对于超过这些尺寸和倾斜角度的储罐，应根据“Coats”方程进行适当的倾斜校正和适当的体积计算。本版API MPMS第2.2E章是ISO 12917-1:2002的国家采用版本。

This Chapter specifies manual methods for the calibration of nominally horizontal cylindrical tanks, installed at a fixed location. It is applicable to horizontal tanks up to 4 m in diameter and 30 m in length. The methods are applicable to insulated and non-insulated tanks, either when they are above-ground or underground. The methods are applicable to pressurized tanks, and to both knuckle-dish-end and flat-end cylindrical tanks as well as elliptical and spherical head tanks.This Chapter is applicable to tanks inclined by up to 10 % from the horizontal provided a correction is applied for the measured tilt.For tanks over and above these dimensions and angle of tilt, appropriate corrections for tilt and appropriate volume computations should be based on the "Coats" equation.This edition of API MPMS Chapter 2.2E is the national adoption of ISO 12917-1:2002.
